Does anyone have a merc o tronic 9800? I’m after some photos of your pcb. I have seen a few online and their are different versions. Mine is missing a component for the condenser leakage test and I’m trying to identify what should be there.
Over on the “Smokstak” web site there was a recent detailed discussion of the Mertronic where the poster basically reverse engineered the thing complete with schematic diagrams.
